Patented pr. 27, 1943 UNITED STATES ATENT OFFICE 1 Claim.

This invention relates to improvements in shoes of the type wherein theinsole is marginally slotted at spaced intervals to receive a pluralityof marginal prongs formed integrally with the upper structure at spacedintervals and has for its general object to provide a shoe of this typewhich will accurately fit the foot and which will exhibit a neat andclose-fitting joint where the upper structure and insole meet eachother. Other objects and advantages of my invention will appear as thedescription proceeds.

In the drawing:

Fig. 1 is a side view showing the upper structure assembled to theinsole and prior to underturning and cementing down the prongs of theupper structure against the under face of the insole.

Fig. 2 is a cross section through the assembly of Fig. 1.

Fig. 3 is a view similar to Fig. 2 but showing the projecting prongs ofthe upper structure as having been turned inwardly and cemented down tothe underface of the insole.

Fig. 4 is a side elevation of a completed shoe.

Referring to Fig. 4, the shoe therein illustrated comprises an outsole2i), heel 2 I, insole 22, and an upper structure of conventional designincluding a vamp 23 and a back 23a.

As shown, the vamp 23 comprises three cross straps 24, 25, and 26 and aslotted toe strap 21 through the slots of which said cross straps areinterlaced, and the back 23a comprises a curved quarter 28 with anklestrap 29 and buckle piece 30 secured to the sides thereof.

The insole 22 has adjacent its marginal edge a plurality ofspaced'elongated pairs of slots 36' cut therein, with intervening websor bridges 35 between said slots. These bridges or webs 35 of the insoleserve as stops to limit the penetration of the prongs 31 at the ends ofthe upper parts 24 to 28 inclusive through the slots 36' of the insole,and also confirm the pitch of the vamp and quarter so as to insureproper tting of the shoe to the last and the foot when I assemble theupper structure and insole, the prongs 31 being drawn through the slots36 of the insole until the webs 31' separating said prongs abut againstthe webs or bridges 35 separating related pairs of slots 36'.

I next apply a coating of cement 39 to the inner faces of the prongs andallow it to dry, after which the prongs are turned inwardly and cementeddown to the underface of the insole (Fig. 3). It will be noted that thepairs of prongs 31 are of a width to snugly t within related pairs ofslots 36 and of a length to extend through said slots and to be foldedagainst and anchored to the bottom surface of the insole when the in- Ysole and upper structure are assembled to each other. It will further benoted that the webs 31 constituting the closed ends of the notchesextend as straight edges which are substantially equal in length to thedistances between the slots of their related slot pairs so that when theprongs are drawn tautly through the slots said straight edges aredisposed at such angles to the transverse axes of the straps as to atlyabut the upper surface of the insole at the line of contact between saidstraight edges and the insole, whereby to correctly position the upperstructure with reference to the insole, as well as assisting to firmlylock the upper structure against longitudinal shifting movementsrelative to the insole.

The structure is now ready to receive the outsole `and heel. Inattaching these parts, a last is rst inserted in the structure and acoating of cement 40 is applied to the outer faces of the inturnedprongs 31 and to the underface of the insole to hold the outsole andheel. The last is then withdrawn resulting in a completed shoe (Fig. 4).

If the insole 22 is of the platform type, I cement as at 4I to the upperface thereof a sheet 42 of decorative material, vas leather, cloth, orthe like, drawing the same around the marginal edge of the insole as at43 and cementing it down to the underface of the insole as at 44. Thisdecorative cover is applied to the insole before the slots 36 are cut inthe insole, and hence is likewise slotted through by the same tool whichcuts the slots 3S in the insole.

Although I have described and shown a shoe of the sandal type, it willbe understood that such disclosure is purely illustrative and in no waylimiting and that shoes of practically any style and design may beproduced by my method.

What I therefore claim and desire to secure by Letters Patent is:

A shoe of the sandal type, comprising an insole having adjacent itsmarginal edge a plurality of spaced elongated pairs of slots, the slotsof each slot pair being spaced apart from one another a substantialdistance, and an upper structure cornprising a series of independenttransversely extending straps, each strap having its marginal edgecentrallyrnotched to provide pairs of spaced prongs, said pairs ofprongs being of a width to snugly t within related pairs of slots and ofa length to extend through said slots and to be folded against andanchored to the bottom surface of the insole when the insole and upperstructure are assembled to eachother, the closed ends of said notchesextending as straight edges which are substantially equal in length tothe distances between the slots of their related slot pairs and whichWhen the several pairs of prongs are drawn tautly through the severalrelated pairs of slots are disposed at such angles to the transverseaxes of the straps as to flatly abut the upper surface of the insole atthe line of contact between said straight edges and the insole, wherebyto correctly position the upper structure with reference to the insole.
